Ecological interactions between cork oak (Quercus suber L.) and stone pine (Pinus pinea L.): results from a pot experiment

  
Forests, Vol. 9, No. 9. (01 September 2018), 534, https://doi.org/10.3390/f9090534

Abstract

Portuguese cork oak (Quercus suber L.) extended mortality and lack of regeneration have been the drivers of important changes in the traditional cork oak woodlands (savanna-like) montado. The decrease in tree cover fosters the mixture with stone pine (Pinus pinea L.) for pine-nut production providing shelter for oak regeneration. The use of nurse species, namely pines, to help Quercus spp. regeneration is known, but whether cork oak could be favoured by the mixture with stone pine remains a question. A pot ...

 

Assessing risk and adaptation options to fires and windstorms in European forestry

  
Mitigation and Adaptation Strategies for Global Change In Mitigation and Adaptation Strategies for Global Change, Vol. 15, No. 7. (10 July 2010), pp. 681-701, https://doi.org/10.1007/s11027-010-9243-0

Abstract

Risks can generally be described as the combination of hazard, exposure and vulnerability. Using this framework, we evaluated the historical and future development of risk of fire and wind damage in European forestry at the national level. Fire risk is expected to increase, mainly as a consequence of an increase in fire hazard, defined as the Fire Weather Index in summer. Exposure, defined as forest area, is expected to increase slightly as a consequence of active afforestation and abandonment of marginal ...

 

Geographic distribution of 24 major tree species in the Mediterranean and their genetic resources

  
(2016)

Abstract

[Excerpt: Introduction] The Mediterranean Basin is one of the world’s richest places in terms of animal and plant diversity. It is a highly diverse region and its mountains, rivers, forests and thousands of islands form a mosaic of natural and cultural landscapes of incomparable value. With around 25,000 species of native plants, of which more than half are endemic, and because many habitats and species are threatened, the Mediterranean is recognized as one of the Global Biodiversity Hotspots [18]. For millennia, ...

 

EUFORGEN Technical guidelines for genetic conservation and use for silver fir (Abies alba)

  
(2003)

Abstract

Since silver fir stands have been regenerated mainly naturally for a long period, there is reason to assume that they have preserved their original genetic structure and diversity, although the genetic composition of silver populations may have been modified by adaptation and/or drift processes. It is evident that in several parts of the distribution area genetic variation has been reduced due to the mentioned decline of silver fir. This reduction of population sizes may have reached a stage where the future ...

 

Combining forest structure data and fuel modelling to classify fire hazard in Portugal

  
Annals of Forest Science, Vol. 66, No. 4. (2009), pp. 415-415, https://doi.org/10.1051/forest%2f2009013

Abstract

Fire management activities can greatly benefit from the description of wildland fuel to assess fire hazard. [\n] A forest typology developed from the Portuguese National Forest Inventory that combines cover type (the dominant overstorey species) and forest structure defined as a combination of generic stand density (closed or open) and height (low or tall) is translated into fuel models. Fire behaviour simulations that accounted for the fire environment modification induced by stand structure resulted in an objective and quantitative assessment of fire ...

 

Planting sentinel European trees in Eastern Asia as a novel method to identify potential insect pest invaders

  
PLoS ONE, Vol. 10, No. 5. (20 May 2015), e0120864, https://doi.org/10.1371/journal.pone.0120864

Abstract

Quarantine measures to prevent insect invasions tend to focus on well-known pests but a large proportion of the recent invaders were not known to cause significant damage in their native range, or were not even known to science before their introduction. A novel method is proposed to detect new potential pests of woody plants in their region of origin before they are introduced to a new continent. Since Asia is currently considered to be the main supplier of insect invaders to ...

Quercus suber range dynamics by ecological niche modelling: from the Last Interglacial to present time

  
Quaternary Science Reviews, Vol. 119 (July 2015), pp. 85-93, https://doi.org/10.1016/j.quascirev.2015.04.018

Abstract

[Highlights] [::] ENM can provide statistical quantitative reconstructions of the species history. [::] New insights suggest the past occurrence of cork oak even in the Levantine. [::] Despite several range oscillations many putative refugia were identified. [::] Past species dynamics are informative for the potential responses to future changes. [Abstract] Ecological Niche Modelling (ENM) is widely used to depict species potential occurrence according to environmental variables under different climatic scenarios. We tested the ENM approach to infer past range dynamics of cork oak, a keystone species of ...

 

Tree species is the major factor explaining C:N ratios in European forest soils

  
Forest Ecology and Management, Vol. 311 (January 2014), pp. 3-16, https://doi.org/10.1016/j.foreco.2013.06.047

Abstract

[Highlights] [::] C:N ratio in forest floor, peat and mineral topsoil mainly depend on tree species. [::] Most important differences in C:N ratios are seen between deciduous and evergreen species. [::] Either soil type, ecoregion or humus type was the second most important explanatory factor. [::] There was no consistent relationship between modelled deposition and C:N ratios. [Abstract] The C:N ratio is considered as an indicator of nitrate leaching in response to high atmospheric nitrogen (N) deposition. However, the C:N ratio is influenced by a multitude of ...

 

Runoff production and erosion processes on a dehesa in Western Spain

  
Geographical Review, Vol. 92, No. 3. (2002), pp. 333-353, https://doi.org/10.2307/4140914

Abstract

Runoff generation and soil erosion were investigated at the Guadalperalon experimental watershed (western Spain), within the land-use system known as dehesa, or open, managed evergreen forests. Season and type of surface were found to control runoff and soil-loss rates. Five soil units were selected as representative of surface types found in the study area: hillslope grass, bottom grass, tree cover, sheep trails, and shrub cover. Measurements were made in various conditions with simulated rainfall to gain an idea of the annual ...

 

Evolution comparée des structures des peuplements mélangés à Quercus suber et Quercus pubescens après élimination du pâturage en forêt de Pisano (Sicile sud-orientale)

  
Ecologia Mediterranea, Vol. 24, No. 1. (1998), pp. 15-25

Abstract

Several studies carried out in north-west Mediterranean areas showed the role of Quercus deciduous species as pioneer woody species in secondary succession processes in abandoned areas. The aim of this paper is to verify this phenomenon in a Quercus suber open woodland in Monti Iblei (South-East Sicily, Italy) where grazing is still present. A diachronie approach was used to study the patterns and growth rate of young individuals (seedlings and saplings) of a deciduous oak (Q. pubescens) and a sclero- phyllous ...

 

Direct regeneration is not the only response of Mediterranean forests to large fires

  
Ecology, Vol. 85, No. 3. (March 2004), pp. 716-729, https://doi.org/10.1890/02-0492

Abstract

It is widely accepted that the postfire recovery in Mediterranean plant communities is carried out by direct regeneration, i.e., the fast recovery of a plant community with the same species pool that it had immediately prior to disturbance. However, there is evidence that not all plant species in the Mediterranean basin survive fire in all situations, suggesting that the direct regeneration process might not apply to all situations. We analyze whether the main combinations of forest tree species (up to 16) ...

 

Resprouting of Quercus suber in NE Spain after fire

  
Journal of Vegetation Science, Vol. 8, No. 5. (October 1997), pp. 703-706, https://doi.org/10.2307/3237375

Abstract

Many Mediterranean species have evolved strategies that allow them to survive periodic wildfires. Quercus suber trees resprout after fire, some from stem buds and others from basal buds only. In the former case the canopy recovers quickly. In the latter case the stem dies but the tree survives and regrows from basal sprouts. The probability of stem death and the degree of height recovery were studied after a fire in a Q. suber forest in NE Spain using logistic regression analysis. ...

 

Reviving extinct Mediterranean forest communities may improve ecosystem potential in a warmer future

  
Frontiers in Ecology and the Environment, Vol. 13, No. 7. (2015), pp. 356-362, https://doi.org/10.1890/150027

Abstract

The Mediterranean Basin is the region of Europe most vulnerable to negative climate-change impacts, including forest decline, increased wildfire, and biodiversity loss. Because humans have affected Mediterranean ecosystems for millennia, it is unclear whether the region’s native ecosystems were more resilient to climate change than current ecosystems, and whether they would provide sustainable management options if restored. We simulated vegetation with the LANDCLIM model, using present-day climate as well as future climate-change scenarios, in three representative areas that encompass a broad ...

 

Erosion in Mediterranean landscapes: changes and future challenges

  
Geomorphology, Vol. 198 (September 2013), pp. 20-36, https://doi.org/10.1016/j.geomorph.2013.05.023

Abstract

[Highlights] [::] Recent land uses contribute to soil erosion in marginal lands. [::] Long history of human activity explains many landscape characteristics. [::] Intensification and extensification/wealth and poverty increase spatial complexity. [Abstract] Intense erosion processes are widespread in the Mediterranean region, and include sheet wash erosion, rilling, gullying, shallow landsliding, and the development of large and active badlands in both subhumid and semi-arid areas. This review analyses the main environmental and human features related to soil erosion processes, and the main factors that explain the extreme ...

Quercus suber

  
In Enzyklopädie der Holzgewächse: Handbuch und Atlas der Dendrologie (1999)

Abstract

Quercus suber ist eine immergrüne, licht- und wärmebedürftige Baumart des westlichen Mittelmeerraumes, die in großem Umfang zur Korknutzung angebaut wird. Korkeichen werden selten höher als 20 m, ertragen Dürre, stellen geringe Bodenansprüche, wachsen aber kaum auf Kalk. In Mitteleuropa sind sie nicht winterhart. Die mehrfach genutzte, stets nachwachsende Korkschicht kann bis zu 4 cm stark werden, und ein einziger Baum liefert während seines Lebens 100 bis 200 kg Kork. Das Holz dient als Brennmaterial, und die Eicheln werden an Schweine verfüttert. ...

Abstract

Biodiversity loss from plant communities is often acknowledged to affect primary production but little is known about effects on herbivores. We conducted a meta-analysis of a worldwide data set of 119 studies to compare herbivory in single-species and mixed forests. This showed a significant reduction of herbivory in more diverse forests but this varied with the host specificity of insects. In diverse forests, herbivory by oligophagous species was virtually always reduced, whereas the response of polyphagous species was variable. Further analyses ...

 

The distribution of Quercus suber chloroplast haplotypes matches the palaeogeographical history of the western Mediterranean

  
Molecular Ecology, Vol. 16, No. 24. (2007), pp. 5259-5266, https://doi.org/10.1111/j.1365-294X.2007.03587.x

Abstract

Combining molecular analyses with geological and palaeontological data may reveal timing and modes for the divergence of lineages within species. The Mediterranean Basin is particularly appropriate for this kind of multidisciplinary studies, because of its complex geological history and biological diversity. Here, we investigated chloroplast DNA of Quercus suber populations in order to detect possible relationships between their geographical distribution and the palaeogeographical history of the western Mediterranean domain. We analysed 110 cork oak populations, covering the whole distribution range of ...

There are nine species of oaks in French forests: Quercus petraea, Q robur, Q pubescens, Q pyrenaica, Q ilex, Q rubra, Q suber, Q coccifera and Q cerris. Among them, five are of major economic and ecological importance, either because of the quality and value of their wood or because of their geographic extension, or both. Two of these species are widespread in the hills and plains of the Atlantic and of the mid-European domains: Q petraea (sessile oak), and Q ...

 

Decline of Mediterranean oak trees and its association with Phytophthora cinnamomi: a review

  
European Journal of Forest Research, Vol. 132, No. 3. (2013), pp. 411-432, https://doi.org/10.1007/s10342-013-0688-z

Abstract

Mortality events in cork and holm oaks have occurred in the Mediterranean basin since the beginning of the XX century, but severity of decline increased during the 1980s. By that time, the exotic soil borne pathogen Phytophthora cinnamomi was often recovered from declining stands and since then it has been considered the main factor associated with decline. This work analyses data concerning P. cinnamomi surveys in cork and holm oaks trees, pathogenicity tests carried out in controlled experiments, studies about the ...

Abstract

Abstract Most atmospheric scientists agree that climate changes are going to increase the mean temperature in Europe with increased frequency of climatic extremes, such as drought, floods, and storms. Under such conditions, there is high probability that forests will be subject to increased frequency and intensity of stress due to climatic extremes. Therefore, impacts of climate change on forest health should be carefully evaluated. Given these assumptions, several fungal diseases on trees may become more devastating because of the following factors: ...

 

Review of oak stand decline with special reference to the role of drought in Poland

  
Forest Pathology, Vol. 28, No. 2. (March 1998), pp. 99-112, https://doi.org/10.1111/j.1439-0329.1998.tb01171.x

Abstract

Declines in oak-forest ecosystems have been reported frequently throughout the world since the beginning of this century. They have been associated with the death of individual trees, of small groups of trees or of entire stands. In this paper, the phenomenon of oak decline is presented in the context of the local site conditions in selected countries. Oak decline is regarded as a result of the synergistic action between damaging agents, both biotic and abiotic. Periodic changes of the climate in ...

The structure and mechanics of cork

  
Proceedings of the Royal Society of London A: Mathematical, Physical and Engineering Sciences, Vol. 377, No. 1769. (25 June 1981), pp. 99-117, https://doi.org/10.1098/rspa.1981.0117

Abstract

The excellence of cork for stopping bottles, for thermal and sound insulation, and as a shock-absorbing material for flooring and packaging is due to the special shape, size and structure of its cells. When loaded, the cell walls bend or buckle, giving large recoverable deflexions and large energy absorption. We have investigated the structure of cork and have measured its moduli and other mechanical characteristics. These can be broadly explained in terms of cell-wall deformation. ...

 

Acorn predation and seedling production in a low-density population of cork oak (Quercus suber L.)

  
Forest Ecology and Management, Vol. 76, No. 1-3. (August 1995), pp. 197-201, https://doi.org/10.1016/0378-1127(95)03566-s

Abstract

Prospects for cork oak recruitment were examined in a scrub-dominated area with low tree density in southern Spain by sowing acorns experimentally in a variety of sites. Seeds placed on the ground surface were invariably eaten within a few months by a variety of vertebrate herbivores (cattle, red deer, fallow deer, wild boar and rabbits). Predation reached 100% whether acorns were placed beneath trees or more than 100 m away from trees. Seeds placed under dense heath scrub were also rapidly ...

Materials, Vol. 2, No. 3. (16 July 2009), pp. 776-789, https://doi.org/10.3390/ma2030776

Abstract

Cork is a material which has been used for mankind for the last 5,000 years and it is a strategic material used for multiple applications, from wine bottles to aeronautics. Many of current cork materials are composites, in particular cork materials for floor and wall coverings and several other building and industrial applications. Recent developments in cork research have shifted from the classical cork-wine relationship to quality and environmental issues, exploitation of cork industry residues and new cork based materials. In ...

Abstract

As climate changes, the effects of forest diseases on forest ecosystems will change. We review knowledge of relationships between climate variables and several forest diseases, as well as current evidence of how climate, host and pathogen interactions are responding or might respond to climate change. Many forests can be managed to both adapt to climate change and minimize the undesirable effects of expected increases in tree mortality. We discuss four types of forest and disease management tactics – monitoring, forecasting, planning ...

 

Cork oak woodlands on the edge: ecology, adaptive management, and restoration

  
(2012)

Abstract

[Excerpt] Scientific research on cork oak and the ecosystems where it thrives is patchy. Results are scattered and usually limited to a single discipline, such as genetics, silviculture, or the physical properties of cork, and the few broad, interregional, multidisciplinary treatments are out of date. The present book is the result of a 4-year European Commission–funded research program (Conservation and Restoration of European Cork Oak Woodlands [.CREOAK], QLKS-CT-2002-01594) that ran from 2002 to 2006. Consortium members included researchers and engineers from ...

 

What limits evaporation from Mediterranean oak woodlands – The supply of moisture in the soil, physiological control by plants or the demand by the atmosphere?

  
Advances in Water Resources, Vol. 30, No. 10. (October 2007), pp. 2113-2122, https://doi.org/10.1016/j.advwatres.2006.06.013

Abstract

The prediction of evaporation from Mediterranean woodland ecosystems is complicated by an array of climate, soil and plant factors. To provide a mechanistic and process-oriented understanding, we evaluate theoretical and experimental information on water loss of Mediterranean oaks at three scales, the leaf, tree and woodland. We use this knowledge to address: what limits evaporation from Mediterranean oak woodlands – the supply of moisture in the soil, physiological control by plants or the demand by the atmosphere? The Mediterranean climate is highly ...

 

Annual variation in soil respiration and its components in a coppice oak forest in Central Italy

  
Global Change Biology, Vol. 8, No. 9. (September 2002), pp. 851-866, https://doi.org/10.1046/j.1365-2486.2002.00521.x

Abstract

In order to investigate the annual variation of soil respiration and its components in relation to seasonal changes in soil temperature and soil moisture in a Mediterranean mixed oak forest ecosystem, we set up a series of experimental treatments in May 1999 where litter (no litter), roots (no roots, by trenching) or both were excluded from plots of 4 m2. Subsequently, we measured soil respiration, soil temperature and soil moisture in each plot over a year after the forest was coppiced. ...

 

Mediterranean cork oak savannas require human use to sustain biodiversity and ecosystem services

  
Frontiers in Ecology and the Environment, Vol. 9, No. 5. (10 June 2011), pp. 278-286, https://doi.org/10.1890/100084

Abstract

Mediterranean cork oak savannas, which are found only in southwestern Europe and northwestern Africa, are ecosystems of high socioeconomic and conservation value. Characterized by sparse tree cover and a diversity of understory vegetation – ranging from shrub formations to grasslands – that support high levels of biodiversity, these ecosystems require active management and use by humans to ensure their continued existence. The most important product of these savannas is cork, a non-timber forest product that is periodically harvested without requiring tree ...

 

Phytophthora cinnamomi and oak decline in southern Europe. Environmental constraints including climate change

  
Annales des Sciences Forestières, Vol. 53, No. 2-3. (1996), pp. 347-358, https://doi.org/10.1051/forest:19960217

Abstract

One of the most destructive of all tree root pathogens, the oomycete fungus Phytophthora cinnamomi, is associated with mortality and decline of Quercus suber and Q ilex in the Mediterranean region. The symptoms and distribution of this decline are described. P cinnamomi is a primary pathogen on a very wide range of trees and woody ornamentals worldwide, but is probably a native of the Papua New Guinea region. It is soil borne and requires warm, wet soils to infect roots. Since ...

Resprouting of Quercus suber in NE Spain after fire

  
Journal of Vegetation Science, Vol. 8, No. 5. (1997), pp. 703-706, https://doi.org/10.2307/3237375

Abstract

Abstract. Many Mediterranean species have evolved strategies that allow them to survive periodic wildfires. Quercus suber trees resprout after fire, some from stem buds and others from basal buds only. In the former case the canopy recovers quickly. In the latter case the stem dies but the tree survives and regrows from basal sprouts. The probability of stem death and the degree of height recovery were studied after a fire in a Q. suber forest in NE Spain using logistic regression ...

 

Modelling the spatial distribution of tree species with fragmented populations from abundance data

  
Community Ecology, Vol. 10, No. 2. (1 December 2009), pp. 215-224, https://doi.org/10.1556/comec.10.2009.2.12

Abstract

Spatial distribution modelling can be a useful tool for elaborating conservation strategies for tree species characterized by fragmented and sparse populations. We tested five statistical models—Support Vector Regression (SVR), Multivariate Adaptive Regression Splines (MARS), Gaussian processes with radial basis kernel functions (GP), Regression Tree Analysis (RTA) and Random Forests (RF)—for their predictive performances. To perform the evaluation, we applied these techniques to three tree species for which conservation measures should be elaborated and implemented: one Mediterranean species ( Quercus suber ) ...

 

Inferring shifts in tree species distribution using asymmetric distribution curves: a case study in the Iberian mountains

  
Journal of Vegetation Science, Vol. 25, No. 1. (January 2014), pp. 147-159, https://doi.org/10.1111/jvs.12079

Abstract

Questions The objectives of this study were to examine altitudinal shifts in tree species distributions over one decade to quantify the potential for tree migration. Location Spain. Methods We analysed presence–absence data using two successive surveys of the Spanish Forest Inventory in five Fagaceae tree species (two temperate: Fagus sylvatica and Quercus petraea, one sub-Mediterranean: Q. faginea and two Mediterranean: Q. suber and Q. ilex) in two mountain ranges (the Pyrenees and the Iberian system). Half of the fitted altitudinal distributions were skewed and required use ...

 

European oak declines and global warming: a theoretical assessment with special reference to the activity of Phytophthora cinnamomi

  
EPPO Bulletin, Vol. 24, No. 1. (1 March 1994), pp. 221-232, https://doi.org/10.1111/j.1365-2338.1994.tb01063.x

Abstract

Causes of current severe declines of the deciduous oaks Quercus robur and Q. petraea in northern and central Europe and of the evergreen Q. ilex, Q. suber and other Quercus spp. in the Mediterranean area are reviewed. Factors implicated include drought, pollution, winter cold, flooding, and stress-related attacks by insects and fungi. Additional factors in Mediterranean oak declines include changing land-use patterns and root disease caused by the aggressive, exotic oomycete root pathogen Phytophthora cinnamomi. Under conditions of global warming the ...

 

Forests of the Mediterranean region: gaps in knowledge and research needs

  
Forest Ecology and Management, Vol. 132, No. 1. (June 2000), pp. 97-109, https://doi.org/10.1016/s0378-1127(00)00383-2

Abstract

Mediterranean forests are characterised by a remarkable set of features that make them naturally and aesthetically attractive, on the one hand, but also quite fragile, on the other, therefore calling for careful strategies for their conservation and management. An exceptionally large variation of environmental conditions characterises the Mediterranean countries, where the environment can limit forest growth and succession but can also give rise, more often than it is supposed, to lush, mesic forest ecosystems, similar to those of central Europe. Moreover, ...

 

Large-scale recruitment limitation in Mediterranean pines: the role of Quercus ilex and forest successional advance as key regional drivers

  
Global Ecology and Biogeography (1 October 2013), pp. n/a-n/a, https://doi.org/10.1111/geb.12111

Abstract

Aim Large-scale patterns of limitations in tree recruitment remain poorly described in the Mediterranean Basin, and this information is required to assess the impacts of global warming on forests. Here, we unveil the existence of opposite trends of recruitment limitation between the dominant genera Quercus and Pinus on a large scale and identify the key ecological drivers of these diverging trends. Location Spain Methods We gathered data from the Spanish National Forest inventory to assess recruitment trends for the dominant species ...

 

Are drought and wildfires turning Mediterranean cork oak forests into persistent shrublands?

  
Agroforestry Systems In Agroforestry Systems, Vol. 76, No. 2. (2009), pp. 389-400, https://doi.org/10.1007/s10457-008-9165-y

Abstract

In the Iberian Peninsula Mediterranean oak forests have been transformed into a mosaic landscape of four main patch-types: forests, savannas, shrublands and grasslands. We used aerial photographs over a period of 45 years (1958–2002) to quantify the persistence and rates of transitions between vegetation patch-types in southern Portugal, where cork oak is the dominant tree species. We used logistic regression to relate vegetation changes with topographical features and wildfire history. Over the 45 years, shrublands have been the most persistent patch-type (59%), and ...
